ing'the removal of dust, orother particles of matter from air or gas.

This invention has utility when. adapted as a dust collector, especially in connection with air cleaning apparatus.

Referring to the drawings: Figure 1- is a perspective view with parts broken away showing an embodiment of the invention:

adapted for use in air cleaning work; Fig.2 is a fragmentary view with parts broken away showing the rear screen frame slightly drawn away from its position adjacent the ends of the ways; Fig. 3 is a fragn'ient'ary view .in elevation of the zig-zag apron; and Fig. at is a view thereof on the line 1V1V of the Fig. ,3.

Leading from the sweeper nozzle, or other dust gathering device is the line 1 discharging. into housing- 2, the lower .portion of which housing is shown as having a large receiving chamber 3, wherein the velocity of air travel is suddenly greatly reduced, at once resulting in a considerable precipitation of the traveling dust, which may be ooca'sionally removed therefrom through the manhole 4. Suspended in said chamber, remote from the-inlet pipe 1, is thezigzag apron or battle 5, having an opening 6 in each of the vallcys facing toward the portion of the chamber 3 receiving the intake 1.

These openings are accordingly in the ridges adjacentthceddy creating valleys on the side of the apron 5 remote from the intak'el. While thereis considerable opening below the balllc 5 allowing air travel to chamber 7, in usual rate of operation, air travel is not so low, but through the openings 6 and about the region of the apron, where the valleys of the /iig-zag bathe create eddies aid- I iug the extraction of dust from the-air. The

air in passing through chamber 7 works its way through a plurality of screens-'8 111 the upper portion ofthe housing to the difl'u sion outlet, comprising a plurality of distributcd openings 9 communicating with the outlet. pipe l0.- This separation of openings,

reduces draftor air travel rate, and thereby materially enhances theefiectlveness of the device by insuring a uniform air d|str bu.

tion through the screens and avoiding local dust raising disturbances, as well as avoiding clogging due to current striking the screens at one point,

The screens are mounted for vibration, to aid in the removal of dust accumulations therefrom. The screens are disposed to obstruct the-dust travel area, sliding in ways 26 the full size ofthc chamber portion. To 'perinit-acce'ss'to said screens, the housing 2 is, provided with a removable end plate 11, having notches 12 therein to permit of firmly locking same in position by the bolts 13. As. thetlz'inged housing is also notched for the bolts 13 along the top and two sides of'the plate 11, slight loosening of said bolts allows of their removal laterally, while loosening of the nuts alongthe lower side will then-permit of raisingjthe end plate upward and then out of position.

The handle 14- is upon rod 15 extending through the-endplate 11, to engage cross brace 16 upon the first screen frame 8. The group of screen frames are held in spaced assembled relation by four rods 17, having spacing sleeves thereon between the frames 8. Engagingthe screen frame remote from brace 16, are two springs 18 extending to have detachable engagci'nent with the h0using 2. These springs may be released by access through handhole 19, to thus allow removal of the screen group for repairs. For vibration of the screen frames, the handle 14 is pulled and released, thereby shaking the full set of screens to cause them to travel in unisgn along-the common ways in .the chamber portion. I

The removable door 2() permits of access for cleaning out the dust receiving chamber 21 disposed below the series of screens. This chamber has slotted openings 22 in the top thereof, through which the dirt from the screens may fall in regular operation, or when handle His pulled outward and released, to give the shaking to the screens" its retracted by=the springs 18.

The top and two sides of the screens 8 are shown of full width of the frame, while the,

fourth or bottom side thereof einbodies'two narrow strips connecting the two sides. ".lhcse strips have an opening or slot 24 thcrcbetween, through which the accumulated dust in the frame may fall, passingregistering slots 22 into dust chamber 21.

The screen proper comprises the clotlr 23 or other substance whichofl'ers but little re- [sistance toairt'ravel, but which will readily stop dust articles. This cloth 2?) is'shown as about t e frame'S in the form of a Ll, be-.

in attached to the two bottom strips at its en 5 and stretched over the top solid "piece 'ofthe frame'between said strips, thereby leaving the slot 24. in communication with the inside of theiframe havin three sides;

closal by frame sides and two 'sides by the Cent-rally of these screening substance. frames and vertically-disposedare brace members 25, to prevent the screening substance 23 from sagging inward to contacteachother and thereby reduce the efiectiveness of-the machine. o What is claimed and it is desired to secure by Letters-Patent is:

1. A dust collector comprising a-lioasing having a re'ceivingchamber provided with an'inletand-a single vertically disposed apron on the side thereof remote from the inletbeing of zigzag contour forming val- Rays and ridges whi'chare vertically extending in said chamber, said ridges being provideztwith openings having the adjacent receding vertical valleys providing eddy creating l)atlles,.to aid in thercmoval of dust from-the incoming air, on each side of said 0 enings, said' valleys facing open areas unlow said screens for receiving dust fromsaid screens.
